The ZoneAlarm Pro package features a firewall, anti-spyware, and identity-theft protection that includes daily monitoring of your credit history. The program normally costs $39.95 for a one-year subscription. The offer, limited to one download per customer, is available here.

“By offering Check Point ZoneAlarm Pro free for 24 hours,” said Laura Yecies, vice president and general manager for Check Point’s ZoneAlarm consumer division, “we are allowing consumers to witness first hand the value and improved protection that comes from our powerful yet easy-to-use firewall.”

This isn’t the first time that Check Point has given away free copies of Zone Alarm Pro. The company made a similar offer last August 12, in observance of one of Microsoft’s “Patch Tuesdays.”

Check Point’s motivations aren’t entirely altruistic, of course; the product the company is giving away operates on a subscription basis and will need to be renewed in one year if it’s to continue delivering value. Assuming this is a subscription program you’re interesting in purchasing, however, that’s at least one year you won’t have to pay for.
